I completely understand; I used to HATE doing leg work, myself. That passed after making a bet with a buddy of mine, and doing a leg workout every 5 days for 6 weeks.
It sounds like you've got the strength and thickness you want, right? If not, get back to basics:
Squats, DeadLifts and Leg Presses.
I've also found Clean-and-Presses to be a good mass builder for the quad/thigh as well a GREAT overall strength builder.
If Quad/Hamstring DEFINITION (cuts/rips)is what you are looking for and you've tried pyramiding (sets of 12, 10, 8, 6, 12) without the results you want, try
this this method:
Drop the weight to 50% of your
1-2RPMax. Do as MANY reps as possible in 1minute, but CONTROL THE WEIGHT. STOP YOUR MOVEMENT BEFORE YOU "LOCKOUT" so you are applying CONTINUAL RESISTANCE ON THE MUSCLE. Rest for 20-30 seconds and repeat this pattern twice
(ie, 2 additional "sets"). If you can't get at least 25reps out in 60secs, drop the weight by 10% until you can. Apply this concept to Leg Extensions, Leg Presses, and Leg Curls. I have been doing this for 2 weeks now (after doing 4 heavy sets of Squats and Deadlifts), and my definition has shot through the roof.
Remember, you MUST switch your routines up every 8-12 weeks. The body adapts to "the routine" after this time. I've started switching mine every 6weeks.
Additionally, make sure your bodyfat % isn't above 16%. The lower your bodyfat is, the more you are going to see your definition THROUGHOUT body's your musculature. The crazy thing is, you may have a genetic disposition to carrying more bodyfat on your legs than anywere else (!!)
if that's the case, you're just going to have to keep sacrificing to burn off more fat. Keep PUSHIN!
